Zeronsd and iOS

I’ve to tried to setup zeronsd on my network, and running into issues with iOS clients. First it’s not possible to enable/disable allowDNS in the iOS client after the network is added. The network first has to be removed, then re-added, at which point allowDNS can be set. After doing that though, when I look at the connection details for a network, the DNS server is not shown. The DNS propagation is working with my other non-iOS clients. Could this be a bug, or could I have misconfigured something?
